3d - 使用 MAXScript 在 3DS Max 2010 中删除 #allKeys 但前 2 个

Question

我一直在使用这个简单的 MAXScript 来清除 3DS Max 2010 上的动画：

deleteKeys objects #allKeys

有没有像这样的简单方法来删除所有关键帧但保留前 2 个？

Answer 1

--Select objects in viewport , run script.
-- it keeps the 2 first keyframes for each controller and removes the rest.

for o in selection do
(
    if (o.position.controller.keys.count > 2) do
    (
        for i = 1 to (o.position.controller.keys.count - 2) do
        (
            deleteitem o.position.controller.keys (i + 2)
        )
    )   
    if (o.rotation.controller.keys.count > 2) do
    (
        temp = (o.rotation.controller.keys.count - 2)
        for i = 1 to temp do
        (
            deleteitem o.rotation.controller.keys (i + 2)
        )
    )   
    if (o.scale.controller.keys.count > 2) do
    (
        temp = (o.scale.controller.keys.count - 2)
        for i = 1 to temp do
        (
            deleteitem o.scale.controller.keys (i + 2)
        )
    )   
)
